HAProxy Open Manager - Testing & Docker Integration

🧪 Test-Integrated Docker Build

Unit tests are now integrated into the Docker build process, ensuring code quality at deployment time.

🔧 How It Works

Backend Dockerfile:

1. Installs test dependencies
2. Runs pytest during build
3. Build fails if tests fail ❌
4. Removes test dependencies for smaller image
5. Continues with production build

Frontend Dockerfile:

1. Installs test dependencies
2. Runs npm test with coverage during build
3. Build fails if tests fail ❌
4. Continues with production build

🚀 Usage

Production Build (with tests):

# Build both services with integrated tests
docker-compose up --build

# Or build individually
docker build -t haproxy-backend ./backend
docker build -t haproxy-frontend ./frontend

Test-Only Build:

# Run comprehensive test suite with reports
docker-compose -f docker-compose.test.yml up --build

# Run backend tests only
docker build -f backend/Dockerfile.test -t haproxy-backend-test ./backend
docker run --rm haproxy-backend-test

# Run frontend tests only  
docker build -f frontend/Dockerfile.test -t haproxy-frontend-test ./frontend
docker run --rm haproxy-frontend-test

Automated Build Script:

# Interactive build with test reports
./scripts/test-build.sh

📊 Test Coverage

Backend Tests (pytest):

• ✅ Soft delete & unique constraints
• ✅ Apply process entity management
• ✅ Entity sync calculations
• ✅ HAProxy config generation
• ✅ Authentication & authorization
• Target: 70% coverage

Frontend Tests (Jest):

• ✅ EntitySyncStatus component
• ✅ ApplyManagement workflow
• ✅ SSLManagement functionality
• Target: 70% coverage

🎯 Build Behavior

✅ Tests Pass:

🧪 Running unit tests...
✅ All tests passed (42/42)
📊 Coverage: 78%
🔨 Continuing with production build...
✅ Build successful

❌ Tests Fail:

🧪 Running unit tests...
❌ UNIT TESTS FAILED - Build aborted
Error: Test suite failed
Build failed with exit code 1

🔄 CI/CD Integration

Azure DevOps Pipeline:

- task: Docker@2
  displayName: 'Build Backend with Tests'
  inputs:
    command: 'build'
    dockerfile: 'backend/Dockerfile'
    tags: 'haproxy-backend:$(Build.BuildId)'
  # Build automatically fails if tests fail

🛠️ Development Workflow

Skip Tests During Development:

# Set environment variable to skip tests
export SKIP_TESTS=true
docker-compose up --build

Run Tests Separately:

# Backend
cd backend && pytest tests/ -v --cov=backend

# Frontend  
cd frontend && npm test -- --coverage --watchAll=false

📋 Test Reports

Backend Coverage: ./backend/htmlcov/index.html Frontend Coverage: ./frontend/coverage/lcov-report/index.html

# Generate and view reports
docker-compose -f docker-compose.test.yml up --build
open backend/htmlcov/index.html
open frontend/coverage/lcov-report/index.html

🚨 Troubleshooting

Build Fails Due to Tests:

1. Check test output in build logs
2. Fix failing tests locally
3. Commit and rebuild

Memory Issues During Build:

# Increase Docker memory limit
docker system prune -f
docker build --memory=4g ./backend

Skip Tests Temporarily:

# Comment out test line in Dockerfile
# RUN python -m pytest tests/ -v --tb=short --disable-warnings || \
#     (echo "❌ UNIT TESTS FAILED - Build aborted" && exit 1)

🎯 Benefits

• ✅ Quality Gate: Broken code cannot be deployed
• ✅ Early Detection: Issues caught at build time
• ✅ CI/CD Integration: Automatic test validation
• ✅ Coverage Reports: Built-in test coverage
• ✅ Production Safety: Only tested code reaches production

This ensures that every deployed image has passed comprehensive unit tests, preventing regression bugs from reaching production.
